To all whom it may concern:

Beit known that I, EDWARD E. DETTE, of Boston, Massachusetts, haveinvented a Sofa- Bedstead, of which the following is a specification: A

My invention has for its object .to construct a sofa that can beformedinto a bedstead by drawing forward the seat with supplementary supports,the back being lowered and the foot and head boards being formedcomplete, all in one operation. A f

Figure 1 is an end elevation, illustrating my invention, as used for asofa, and showin g, particularly, the arrangement for raising thepieces, which, in connection With the arms, form the head and footboards. Fig. 2fis a vertical section through the middle of the sofa online 2 2, Fig. 4, and parallel to the plane of the end, showing moreparticularly the manner of folding the backv onto the seat, and themeans for lowering the back to form the bedstead. Fig. 3 shows theparts, `in position, to

be used for a bedstead. Fig. AL is a front elevat-ion of the sofa. Fig.5 is a longitudinal vertical section on line l l of Fig. 1, lookingtoward the rear.

The stationary frame-work N has the ends A suitably stayed by the bottomce and crosspieces b c. The Seat e, on which the cushion t is fastened,is connected firmly with the slides B. These slides move inside the endsA on cross-pieces or ways C. The slides B are connected firmly with thesupports D. The armsE are also connected to the slides B by beingpivoted to the seat e at f. Pieces F, which are Similar to the arms, andare with the arms E to complete the head and footboards, are pivoted tothe frame-work N at g, and also hinged to the arms at It. The ends ofthe frame N are so constructed as to form a casing, int-o which thepieces F drop, as shown by the dotted lines in Fig. l. rEhe back G, onwhich the cushion P is fastened, has joined to it the endpieces H,which, when dropped down into a horizontal position, correspond to theslides B and move on the Ways C. Connected With Vthe pieces H, andhence, With the back G, are the guides I. These guides are connectedwith the guides B by the links K, which are hinged to the guides B at j,and to the guides I at k. The guides I move on the roller (or a iixedbar or bars) L. The bedstead is formed from the sofa by simply drawingforward the seat e, which, with the supports D and 'slides B, all moveas one. At the same -time the arms E rise alittle, turning about-thepivots f, allowing the pieces F to turn about the pivots g and bringthem, by means of the hinges h, to their place. guides I also move alongon the roller L, lowering the back to a level with the seat, the backbeing hinged to the seat at m.

I claim as my inventionl. In combination with the stationary frame- WorkN, consisting of the ends A, bottom a, cross-pieces b c, and guidewaysG, the sliding framework consisting of the supports D, slides B, andseat'e, and the hinged back G, arms E, and pieces F, all constructed andarranged in the manner and for the purpose described.

2. In combination with the roller L, secured to the stationary frame N,the guides I pivoted to the end pieces H of the back G and connectedwith the slides B bythe links K, in the manner and for the purposedescribed.
